HH-THT30天然气 加臭剂四氢噻吩含量的测定 在线取样气相色谱法

HH-THT30天然气 加臭剂四氢噻吩含量的测定 在线取样气相色谱法 详细信息：

名称·：毛细管柱
规格：30m*0.32mm
型号：HH-THT30
应用：天然气中四氢噻吩测定  气相色谱法

浩瀚色谱（山东）应用技术开发有限公司采用冷冻聚焦-硫发光检测器气相色谱仪测定环境空气与无组织排放中硫化氢等16种含硫化合物。结合大体积(5 mL)进样,对仪器条件进行研究。结果表明:在佳条件下,16种含硫化合物的相关系数均>0.997,方法检出限为0.14~0.59μg/m3,相对标zhun偏差为0.7%~4.6%。且硫化氢、羰基硫、jia硫醇、jia硫醚、二jia基er硫醚、二硫化碳、噻吩、四氢噻吩这8种化合物的检出限均小于嗅阈值,解决了能够闻到含硫化合物的臭味,却检测不出的难题。该方法提高了检测精度,适用于环境空气与无组织排放中痕量含硫化合物的测定。

HH-THT30 natural gas odorant - Determination of tetrahydrothiophene content - Online sampling gas chromatography method

HH-THT30 natural gas odorant - Determination of tetrahydrothiophene content - Online sampling gas chromatography method - Detailed information:

Name: Capillary Column

Specification: 30m * 0.32mm

Model: HH-THT30

Application: Gas chromatography method for the determination of tetrahydrothiophene in natural gas

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a cryogenic focusing sulfur luminescence detector gas chromatograph to determine 16 sulfur-containing compounds, including hydrogen sulfide, in ambient air and unorganized emissions. Study the optimal instrument conditions by combining large volume (5 mL) injection. The results showed that under optimal conditions, the correlation coefficients of 16 sulfur-containing compounds were all>0.997, the detection limit of the method was 0.14-0.59 μ g/m3, and the relative standard deviation was 0.7% -4.6%. And the detection limits of eight compounds, including hydrogen sulfide, carbonyl sulfide, jia thiol, jia sulfide, di jia er sulfide, carbon disulfide, thiophene, and tetrahydrothiophene, are all below the odor threshold, solving the problem of being able to smell the odor of sulfur-containing compounds but not detect them. This method improves detection accuracy and is suitable for the determination of trace sulfur-containing compounds in ambient air and unorganized emissions.
